Doesn't show a reason for that. Which IOS is that ? You can also try isdn tei-negotiation preserve under bri. Also check a debug cch323 if something is going on on that side.

May be stupid question but you have DSP in the box ?

Cannot really suggest a reason why that is happening.

Yes

Any chance to try another release like 12.4(3) latest ?

I don't think I ever seen that happen.

This ios working very well on two another routers. I copy config from them.

After reload CALL_PROC are transmited, but I get new error. I try to solve new problem.

Reload is helping me.

Thank you very much
